VETERINARY OPERATING-TABLE.

SPECIFICATION forming part of Letters Patent No. 407,610, dated July 23,1889.

Application iiled October 22, 1888. Serial No. 288,827. (No model.)

To CLM whom t may concern:

Be it known that I, DAVID It. PRICE, of Cambria, in the county ofColumbia, and in the State of Visconsin, have invented certain new anduseful Improvements in Veterinary Operating-Tables; and I do herebydeclare that-the following is a full, clear, and exact descriptionthereof. l

My invention relates to veterinary surgical tables; and it consists inlcertain peculiarities of construction, as will be fully set forthhereinafter, and pointed out in the claims. j

In the drawings, Figure l is an end elevation of my device, partly insection, on the line l l of Figs. 3 and 4L, and with the table proper ina vertical position, and showing a horse being secured thereto. Fig.2 isan end elevation of my device, with the table proper and horse securedthereto, adjusted at an angle. Fig. 3 is a plan view of the table properin a horizontal position, partially broken away to show the constructionand arrangement of some of the parts beneath. Fig. 4 is a verticalsection on the line l il: of Fig. l, and Fig. 5 is a detail view of oneof the body-straps and its fastening device.

A A represent the legs or vert-ical posts of a suitablesupporting-frame, having suitable end braces B B and side braces C C,which latter are further connected by the cross-tim# bers D D, and tothe top of the posts A A are secured the beams E E, projecting,preferably, beyond said posts at each end, and connected at their rearends by the beam F, which latter is perforated to receive a rod G,passing therethrough and through a suitable bearing II, rising from thecrosstimbers D D and terminating in a worm-gear I, which is in mesh withthe teeth of a gear-wheel J, supported between the said cross-timbers DD on an axle K, suitably j ournaled to said timbers, as shown at a ce,the rod G passing through a bearing b in the beam F, and having a crankL or other power attached to its rear end.

M is the operating-table proper, preferably of the shape shown in thedrawings, and suitably padded or cushioned, as shown at N, on its upperor outer side, and having cleats O O on its under or inner side, wherebyit is pivoted by the rodP to the inner ends of the top beams E E of thesupporting-frame, and between these cleats O O is a lug or boss Q,

(secured, as by bolts 0 o, to the table M,) to which are pivoted on thejournal c the inner ends of the links R R, whose other ends straddle thegear-wheel .I and are pivoted thereto by the journal d.

S is a rod passing through the lower ends of the cleats O O, and havinga crank e at its outer end, and adjacent thereto, outside the cleat,carrying a ratchet f, which engages with a slotted spring-pawl g,secured to the adjacent end of the table M. Secured to this rod S arefour chains 71, h, arranged in pairs near each end and passing throughholes t' t' in the said table M, and at the free ends of these chainsare secured hopplesT T, adapted to buckle around the feet of the horseor other animal to be operated upon. When these hopples have beenadjusted, as shown in Fig. l, then the rod S is turned by means of itscrank e, and the four feet of the animal are thereby drawn against thetable H, as in Fig. 2, the chains h h winding on the rod S, and the pawlg preventing them from being accidentally loosened.

The upper portion of the table M is provided at each side with the holesj j, arranged in pairs, and through one of these pairs of holes(according to which side the animal is to present while being operatedupon) there is passed the n eck-strap II, and this is buckled around theanimals neck, as shown.

V V are the body-straps, arranged in series, (three, more or less, aboveand a corresponding number below,) whose inner ends are preferably madefast to the table M before the cushion N is applied thereto, as shown inFig. l and at V? in Fig. 3, and their free ends passed out through holesor slits 7c k in said cushion, and the ends of the upper straps V carryclamping-plates m at their ends, in whose side edges are j ournaledcam-rollers IV, having convenient lever-handles fn, so that when thestraps V are passed around the body of the animal and the ends of thesestraps slipped under the Vcam-rollers the latter can be instantlytu-rned and the strap ends tightened to place, this being a much moreconvenient arrangement than tying or buckling said ends.

The operation of my device will be readily understood from the foregoingdescription of its construction. When the animal is to be IOO operatedupon, the table M must be in the vertical position shown in Fig. l andthe animal strapped and hoppled thereto, as shown and described. Then byturning the crank L, or otherwise revolving the rod G, the said table Mis inclined to any angle preferred, and in whatever position it may beleft, either vertical, angular, or horizontal, it will be rigidlysustained without any adjustment or locking of parts, as in mostoperating-tables, and at the same time present an unobstructed surfaceto the operator.

Vhile I prefer to use chains, as shown at 71, to connect the hopples Tto the rod S, it is obvious that I may use cords, ropes, or cables, thesaid rod serving as a winding-drum for whatever iiexible connections areused, and as the latter are practically of equal length a few turns ofthe said rod will serve to draw all the feet of the animal snuglyagainst the operating-tablc- Having thus described my invention, what Iclaim as new, and desire to secure by Letl. The combination, with aveterinary operating-table, of a rod journaled in suitable bearings inthe lower part thereof, chains or cords of practically equal lengthconnected to said rod, hopples connected to the free ends of said chainsor cords, and means for revolving said rod and holding it in any desiredadjustment, substantially as set forth.

2. The combination, with a suitable supporting-frame, of a veterinaryoperating-table hinged to a horizontal rod on said frame below thelongitudinal center of said table, a gearwheel mounted on a horizontalaxle in said fra'me and carrying a transversely-projecting journal nearthe periphery of said wheel, a journal secured to the rear or under sideof the operating-table above the plane of said gear-Wheel, a pair ofinflexible links pivoted to the last-named journal and straddling thegear-wheel and pivoted to the transverse proj ecting journal thereon, ahorizontal rod mounted in the frame above the gear-wheel and carrying atthe inne'r end a Worm-gear rigid with said rod and in mesh with saidgear-wheel, and a crank fixed to the other end of said rod,substantially as set forth.

3. The combination, with an adjustable veterinary operatingtableprovided with a pad or cushion covering its entire outer surface, andhaving holes arranged in pairs at each side of its upper portion andaseries of holes arranged in pairs at each side of its lower portion, ofa neck-strap passing through one of the upper pairs of holes,body-straps arranged in upper and lower series .secured to the table andpassing through slits or openings in the cushion, and the straps of oneseries having clampingplates and cam-rollers at their free ends, chainsor cords of practically 'equal length passing through the holes in thelower portion of the table and carrying' hopples at their outer ends,atransverse revolving rod located adjacent to said lower holes andjournaled in cleats or bearings on said table and connected to the innerends of said chains or cords, a ratchet on said rod, and a springpawl onsaid table adapted to engage with said ratchet, substantially as setforth.

In testimony that I claim the foregoing I have hereunto set my hand, atCambria, in the county of Columbia and State of lVisconsin, in thepresence of two witnesses.
